TECHNICAL FIELD

[0001] The utility model relates to a clamping device belongs to electronic equipment accessories field. BACKGROUND

[0002] In modern society, with the continuous improvement of people's living standards, in the scene of going out for travel, participating in activities, etc., taking photos has become a common demand. Selfie stick as a common photographing auxiliary tool, its market demand continues to grow. However, the existing selfie stick has some obvious shortcomings in design and function, which limits the user's experience and further promotion of the product.

[0003] Firstly, the portability of selfie stick is a prominent problem. The length of traditional selfie stick in the folded state is relatively long, which makes the user need to occupy a large space when carrying, especially when traveling needs to be frequently stored and taken out for use, the overlong selfie stick will bring many inconveniences to the user. In addition, the longer selfie stick is also difficult to find a suitable storage position when storing, which is easy to interfere with other items, causing damage or loss.

[0004] Secondly, the design of the selfie stick clamp cannot meet the clamping needs of various mobile phone sizes. With the continuous development of smart phones, the screen size of mobile phones shows a trend of getting larger and larger, while the traditional selfie stick clamp often cannot provide enough supporting force and stability when clamping large-screen mobile phones, which is easy to cause the mobile phone to slip and be damaged. At the same time, for some small-screen mobile phones, the clamping space of the clamp is too large, which cannot realize accurate clamping and affects the shooting effect. This limitation on the size of the mobile phone makes the user need to buy a suitable selfie stick after changing the mobile phone of different sizes, which increases the use cost.

[0005] Thirdly, the structure of the existing selfie stick clamp is relatively cumbersome, the appearance is not beautiful enough, and it lacks flexibility and multifunctionality. The traditional clamp design cannot realize multi-angle rotation and adjustment, and the user is difficult to find the best angle when shooting, which limits the creativity and effect of shooting. In addition, some selfie stick clamps also have deficiencies in material and process, which leads to short service life and is easy to have problems such as loosening and deformation, which affects normal use.

[0006] In summary, the existing selfie stick has many problems in portability, clamping compatibility, flexibility and appearance, and an improved clamping device and selfie device are needed to meet the increasingly diversified needs of users and improve the market competitiveness and user experience of the product.
